From SPSS to jamovi: Analysis of Covariance (ANCOVA)

This comparison shows how to test if the covariate is independent of the independent variable, as described in chapter 13.5.3 of Field (2017), especially output 13.3. It uses the data set Puppy Love Dummy.sav which can be downloaded from the web page accompanying the book.
SPSS jamovi
In SPSS you can run this test using Analyze → Compare Means → One Way ANOVA. In jamovi you do this using: Analyses → ANOVA → ANCOVA.
SPSS_Menu_ANCOVA2 jamovi_Menu_ANCOVA2
In SPSS, move Puppy_love to the variable box Dependent List and Dose to the variable box Factor. In jamovi, move Puppy_love to the variable box Dependent Variable and Dose to the variable box Fixed Factors.

When comparing the outputs in SPSS and jamovi, the results are exactly the same. The only difference is that jamovi does not provide a row with the total sum of squares and degrees of freedom.

In the ANCOVA table, you can find the degrees of freedom between groups and within groups, as well as the F-value and its significance level. The results from this analysis indicate that for all three puppy therapy groups, the love for puppies were about the same. In jamovi, these values are found in the equivalent table (ANCOVA – Puppy_love).

In both SPSS and in jamovi, the degrees of freedom can be found in the second, the F-value in the fourth, and the p-value in the fifth column.

The numerical values are the same in both SPSS and jamovi: F*(2, 27) = 1.98, *p = 0.16.
If you wish to replicate those analyses using syntax, you can use the commands below (in jamovi, just copy to code below to Rj). Alternatively, you can download the SPSS output files and the jamovi files with the analyses from below the syntax.
